SPECIFICATION forming part of Letters Patent No. 268,898, dated December 12 1882.

l Application filed May 9, 188i?. (No model.) I l 'My invention relates to a new and useful evener-hinge, which is especially adapted for section-narrows; and it consists in certain precise details ot' construction, as hereinafter fully described, and particularly pointed out in the cla-im.

The object of my invention is to furnish a connection between the evener and any Vnumber of independentsectionsof aharrow,where by each section may vibrate freely without the employment ot' side hinges, and at the same time each may be readily raised to be cleaned without interfering with the others.

Harrows are usually constructed of a number of sections independent ofeach other to a certain extent. The evener is usually clipped by links to the frontcenter of each section. It' this were the only connection, each section would have too great play, and its vibration as 1t dragged along over clods, &c., would frequently be so great as to cause damage to the other sections. To provide for this alink-connection of various descriptions is made between two sections'alon g their adjoining sides. This keeps each `to a limit of vibration, but is objectionable from the fact that it not only limits side movement, but end movement as well, and thereby prevents the section from being raised to be cleaned, as it requires considerable strength to raise the whole'harrow. My invention limits the side movement of the sections, and yet allows each to be raised independently of the others.

Referring lto the accompanying drawings,` Figure 1 shows the application of my device open frame, in the rear end of which is verti cally journaled a roller or spool, c. Before the clips E are bolted to the evener the curved links are fitted through and draw against the spools e. This connection forms a hinge which allows all the side movement or play of the sections which is necessary, and enables me to dispense with side hinges. They can easily vibrate; but because of the hinges being at the ends of the front they arel prevent-ed from swinging too freely. Having no side hinges, each section may be raised independently of the others. The rollers e reduce the friction and keep` the links and clips from Wearingout.

They allow the curved links to move from side I
